Extermination of large predators such as wolves and bears has a cascading effect on delicate ecological balance

A plea to restore populations of some of the world's most dangerous animals has been made by scientists who claim the loss of large carnivores is damaging ecosystems.

More than three-quarters of the 31 species of large land predators, such as lions and wolves, are in decline, according to a new study. Of these, 17 species are now restricted to less than half the territory they once occupied.

The twins were found alive by fishermen on the Baja California peninsula but lived only a few hours

Fishermen in Mexico have found rare conjoined grey whale calves that died shortly after being born.

The bluefin tuna auctioned off this weekend in Japan was comparatively 'cheap', but the price can't be used as a yardstick for its conservation status

Each January for the last several, we have celebrated the New Year with unlimited excess—not only the gluttonous, gammony kind, but the excess which heralds the year's first auction of a gargantuan bluefin tuna at the Tsukiji Fish Market in Tokyo, Japan. Each time, one fish, whose flesh is prized as an expensive delicacy in sushi restaurants, becomes a symbol of the New Year in this way.

Last January's tuna sold for a record-breaking £1.1 million (155.4 million yen), more than double the price it claimed in 2012, upholding a tradition that has seen that initial coveted bluefin growing increasingly expensive each year.

The shepherds' ancient foe is back in numbers – and now packs are breeding a mere 40 miles from Madrid

A twig snaps, a crow calls, but nothing moves in the dense pine forests of Spain's Guadarrama mountains. Vultures and eagles soar over the snowcapped peaks and wild boars roam the valleys below, as they have for centuries. But for the farmers who work this land, a threatening and worrying comeback is taking place in this timeless landscape, home to Spain's newest national park.

After an absence of 70 years, the wolf is back in the Guadarrama hills and breeding just 40 miles from Madrid.

Commentators say plight of MV Akademik Shokalskiy shows global warming is exaggerated – the truth is not that simple

To most people the prolonged stranding of the MV Akademik Shokalskiy in thick pack ice off the coast of Antarctica is an unfortunate incident that provided passengers with rather static scenery for their Christmas and New Year celebrations.

But to some climate change contrarians, repeated attempts to free the vessel from the ice are proof that the theory of climate change is flawed or, at best, exaggerated. After all, a warming planet has no ice at all, right?

Seaham, Durham: Almost a century after the bottleworks closed, the sea still returns the waste glass that was routinely dumped into sea

When Dawdon pit closed and the sea dumping of colliery waste ended, Blast beach resembled the surface of an alien planet – so much so that it was chosen as the location for the opening sequences of the 1992 movie Alien 3. Since then a massive clean-up campaign has transformed the shore into a pleasant place for a Christmas-morning walk, graced today with dazzling sunshine. At the bottom of the cliffs there are still traces of industrial archaeology: some topsy-turvy geology with boulders brought to the surface from strata below the magnesian limestone cliffs; colourful mineral incrustations; a faint whiff of sulphur. But with every tide the sea erases a little more of the decades of industrial abuse, and also delivers small, sought-after gifts.

Nausea, headaches and nosebleeds, invasive chemical smells, constant drilling, slumping property prices – welcome to Ponder, Texas, where fracking has overtaken the town. With the chancellor last week announcing tax breaks for drilling companies, could the UK be facing the same fate?

Veronica Kronvall can, even now, remember how excited she felt about buying her house in 2007. It was the first home she had ever owned and, to celebrate, her aunt fitted out the kitchen in Kronvall's favourite colour, purple: everything from microwave to mixing bowls. A cousin took pictures of her lying on the floor of the room that would become her bedroom. She planted roses and told herself she would learn how to garden.
